Intervention Study on Hypertension Management Combined With Health Promotion at Commune Level

Overview

A quasi-experimental study design was chosen to compare the model of hypertension management at commune-level with conventional management for people with high blood pressure in two communes (one for intervention versus one for reference).

A intervention model included the commune-based programme on hypertension management combined with comprehensive health promotion campaigns

Detailed Description

A quasi-experimental study design was chosen: two communes were purposively selected from Ba-Vi setting: Phu-Phuong for reference and Phu-Cuong for intervention communes A hypertension management programme and the nested comprehensive health promotion campaigns were implemented simultaneously in Phu-Cuong while nothing performed in Phu-Phuong except for local conventional healthcare services.

The health promotion campaigns aimed at smoking cessation, reduction of alcohol consumption, encourage of unsalted diet and physical activity, all of which targeted to every local inhabitants.

The hypertension management programme focused on monthly check-ups, drug delivery and individual lifestyle consultation, all of which targeted to hypertensives only.

Baseline cross-sectional survey was used to assess cardiovascular pattern in local community before intervention and recruit people with high blood pressure for the management programme in intervention commune Repeated cross-sectional surveys were used to evaluate the impacts of health promotion.

Cohort study on hypertensives was used to evaluate the impacts of the management programme.

Interventions

  • Other: Commune Hypertension Management
    • People with high blood pressure will be invited to join the management programme, with monthly check-up, delivery of multi anti-hypertensive drugs and lifestyle consultation. Antihypertensive drugs delivered to local patients included (1) low-dose hypothiazide diuresis, (2) calcium channel blocker and (3) ACEI

Arms, Groups and Cohorts

  • No Intervention: Conventional Healthcare services
    • People with high blood pressure detected during screening survey or opportunistically during study period will be referred to receive the conventional health care services for hypertension at district hospital or local commune health station
  • Experimental: Commune Hypertension Management
    • People with high blood pressure were managed in commune-based hypertension management programme
